Paperback. Condizione: New. Print on Demand. This book describes a range of materials that can be used to simulate the electrical properties of the human body in the frequency range of 100 Hz to 10 MHz and a temperature range of 15 °C to 40 °C. These materials are intended for use in the development and evaluation of medical devices and metal detectors. The author details the results of a study on various mixtures of materials, including potassium chloride solution, a mixture of ethylene carbonate, propylene carbonate, and salts, a semi - solid nano -composite material consisting of semi - solid silicone rubber filled with carbon black particles, and a mixture of glycine, carrageenan, and potassium chloride, in water. The author provides valuable data on the conductivity, permittivity, and temperature dependence of these materials, and discusses the advantages and disadvantages of each type of material for use as a phantom material. The book includes a comprehensive analysis of the electrical properties of conductive materials, a review of mixture theories for conductive materials, and a discussion of the applications of phantom materials. The author's insights on the electrical properties of the human body and the development of phantom materials are significant contributions to the field of medical device and metal detector research.

Paperback. Condizione: New. Print on Demand. This book offers theoretical models for predicting low-frequency dielectric behavior in a futuristic material: carbon-loaded polymer composites, which are being investigated for use in semisolid human phantoms. The author begins with an overview of the effective medium formulations of Lorentz-Lorenz, Clausius-Mossotti, Maxwell-Garnett, and Bruggeman, highlighting their key differences. They adapt the Clausius-Mossotti and Bruggeman formulations to account for disordered cluster suspensions, a relevant development for these composites, as carbon black may form electrically conductive clusters that depend on the total loading. These models hold application to conductive carbon particle and insulating polymer composites, which are currently being tested for use in human phantoms. The book concludes by comparing the adapted aggregate forms of the Clausius-Mossotti, Bruggeman, and Maxwell-Garnett theoretical effective permittivity predictions with room-temperature laboratory dielectric data obtained on carbon-silicone composites.
